| Description: | KIT, KIT mutant, and PDGFRα mutant kinase profiling was performed with recombinant enzymes including wild-type KIT, KIT V560G, KIT V559D/T670I, V559D/V654A, and PDGFRα D842V. Kinase/substrate pairs were prepared in reaction buffer (20 mM Hepes (pH 7.5), 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSO). Compounds were dissolved at 10 mM in 100% DMSO, serial diluted and added to the kinase/substrate mix in final concentrations from 10 uM to 0.5 pM. Compounds were incubated with the recombinant enzymes and substrates at room temperature for 20 minutes with their respective Km for ATP. 33P-ATP (10 mCi/mL) was added to initiate the reaction. |
